Hi,
I'm sorry that your last sober experience was miserable and lonely. I hope this time can be different for you and very positive. I lucked into a volunteer job in my very early recovery and I was amazed by how much it helped me. I met some wonderful (sober) people and I began to feel like I had a purpose in my life.
It's good that you recognize that you are vulnerable right now, and hopefully you can make some changes in your life so that your recovery is an awesome experience.
